Freescale Semiconductor introduces Qorivva MPC5604E 32bit MCU that incorporates Ethernet connectivity and video compression to transmit high resolution compressed video data over fast Ethernet for a 360° view around the vehicle enabling reduced costs and safe, efficient parking to a broader range of vehicle models.

Typically for transmission of video, a vehicle needs four or five low voltage differential signalling cables at a cost of roughly Rs.446.43 ($10) per cable. By compressing and transmitting the video signals via Ethernet, it eliminates the need for cables and saves on the bill of materials.

By using Ethernet two wire networks, automakers can reduce material expenses and lower weight while improving performance. The adoption of Ethernet is an important step in the migration from a closed application to an open and scalable driver assistance network in which several systems can easily access information from a sensor.

"Freescale is committed to providing embedded processing solutions that help automakers reduce their costs and proliferate advanced safety features for consumers," said Ray Cornyn, director of Freescale's automotive MCU business. "This newest MCU in our Qorivva 32bit MCU portfolio will help the auto industry bring 360° parking assist systems to more of the mainstream market."

The Freescale Qorivva 32bit MCU sits next to multiple cameras placed around a vehicle, allowing direct interface to a CMOS image sensor. Once video images are captured, the video data is compressed using lowest latency motion JPEG compression and then ultimately sent over the 2 wire Ethernet cable. Hardware assisted AVB compliant time stamping helps to ensure accurate real time communication, as well as synchronisation of the camera exposure.

"Freescale and BMW have cooperated on the definition of several generations of MCUs targeted at automotive networking," said Thomas Koenigseder, senior systems architect, Networks at BMW. "The MPC5604E is the outcome of the latest cooperation between the two companies and will help establish Ethernet as a dependable long term solution for broadcast of video and other forms of data around the automobile."

The Qorivva MPC5604E 32bit MCU extends Freescale's portfolio of MCUs designed for the rapidly growing market known as advanced driver assistance systems (ADAS). In March, Freescale announced the Qorivva MPC567xK family for advanced driver assistance systems and the Qorivva MPC56xB/C/D family designed to significantly reduce the security risks of automotive electronics tampering.

Each Qorivva 32bit MCU comes with a full run time software solution, including AUTOSAR MCAL driver suites and AUTOSAR real time operating system for single core and multi-core MCUs. Qorivva MCUs also are supported by development tools, including high performance compilers and multi-core debuggers from Freescale development partners and Freescale's CodeWarrior development studio.

The MPC5604E devices are currently available from Freescale in sample quantities.
